|---|---|---|---|---|---|
| CVE-2026-53702 | A stack buffer overflow flaw was found in the GStreamer H.265 codec parser library (gst-plugins-bad). When parsing a buffering period SEI message, the parser uses an incorrect loop bound derived from cpb_cnt_minus1[i] (the loop index) instead of the sub-layer 0 CPB count cpb_cnt_minus1[0] from the referenced Sequence Parameter Set. A crafted H.265 video file or stream can cause the parser to write beyond the bounds of stack-allocated CPB delay arrays, resulting in a crash or potential stack memo | 6.5 | 无 | 2026-06-11 | 2026-06-11 |
| CVE-2026-53701 | An out-of-bounds write vulnerability was found in GStreamer's H.266/VVC PPS picture partition parser in gst-plugins-bad. In the multi-slice-in-tile processing of gst_h266_parser_parse_picture_partition() (gsth266parser.c), the loop iterates without checking that the slice index stays within bounds, writing past three fixed-size arrays (slice_height_in_ctus, slice_top_left_ctu_x, slice_top_left_ctu_y) in the GstH266PPS structure. While the initial proof-of-concept demonstrated a 4-byte out-of-bou | 6.5 | 无 | 2026-06-11 | 2026-06-11 |
| CVE-2026-11774 | An integer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), adding sizeof(uint32_t) to a crafted SASL packet length prefix of 0xFFFFFFFC causes unsigned wraparound to zero, bypassing the nsslapd-maxsasliosize limit and leading to a heap buffer overflow of up to approximately 2 megabytes of attacker-controlled data. After a successful SASL bind with integrity protection (SSF > 0), a remote attacker can cause a Denial of Service (DoS) | 7.6 | 无 | 2026-06-11 | 2026-06-11 |
| CVE-2026-11986 | A flaw was found in the admin-ui-ext component of Keycloak, which provides extended administrative user interface capabilities. The issue occurs because certain bulk role-removal endpoints fail to perform granular permission checks when deleting role mappings. This allows a delegated administrator with limited permissions to remove highly privileged roles from other users or groups, potentially disrupting administrative access control. | 4.9 | 无 | 2026-06-11 | 2026-06-11 |
| CVE-2026-11850 | An integer underflow vulnerability was found in MIT krb5 in the berval2tl_data() function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c. The function performs an unsigned subtraction (bv_len - 2) without a prior bounds check. When bv_len is 0 or 1, the subtraction wraps to a large value which is then truncated to uint16_t, yielding 0xFFFE (65534) or 0xFFFF (65535). The subsequent malloc succeeds and memcpy reads up to 65534 bytes from a 0-1 byte buffer, resulting in a heap out-of-bounds read | 5.0 | 0.03% | 2026-06-11 | 2026-06-11 |
| CVE-2026-6893 | A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the s | 8.8 | 0.16% | 2026-06-10 | 2026-06-10 |
| CVE-2026-53476 | A flaw was found in assisted-migration-agent. An unauthenticated attacker, located on the same local area network (LAN), can exploit a path traversal vulnerability. By crafting a specially designed gzipped tarball, the attacker can bypass security checks and write arbitrary files to the system. This could ultimately lead to the execution of unauthorized code on the appliance. | 9.6 | 0.05% | 2026-06-10 | 2026-06-10 |
| CVE-2026-53475 | A flaw was found in assisted-migration-agent. The application hardcodes insecure Transport Layer Security (TLS) connections when communicating with vCenter. This vulnerability allows a Man-in-the-Middle (MITM) attacker to intercept and harvest vCenter administrator credentials. This can lead to unauthorized access to vCenter. | 9.3 | 0.01% | 2026-06-10 | 2026-06-10 |
| CVE-2026-53474 | A flaw was found in migration-planner. A remote authenticated attacker could exploit this vulnerability by uploading a specially crafted RVTools .xlsx file. Due to improper input sanitization, malicious SQL embedded within a spreadsheet cell is executed when cluster names are processed. This SQL Injection allows for arbitrary file reading on the system, potentially exposing sensitive information such as Kubernetes service account tokens and other credentials, which could lead to a full compromis | 9.6 | 0.03% | 2026-06-10 | 2026-06-10 |
| CVE-2026-53473 | A flaw was found in migration-planner-ui-app. An attacker can register a malicious discovery agent with a specially crafted credentialUrl containing JavaScript code. When an organizational user clicks this link in the user interface, the embedded malicious code executes within the user's browser session. This cross-site scripting (XSS) vulnerability allows the attacker to compromise the victim's Red Hat Single Sign-On (SSO) session, potentially leading to unauthorized cross-tenant data access an | 7.3 | 0.03% | 2026-06-10 | 2026-06-10 |
| CVE-2026-53471 | A flaw was found in migration-planner. The agent-API middleware processes JSON Web Tokens (JWTs) for authentication, but its UpdateSourceInventory and UpdateAgentStatus handlers fail to validate the source_id claim within these tokens against the requested source ID. This oversight allows an authenticated attacker with a valid agent token to manipulate data across different tenants, leading to a complete collapse of tenant isolation. This could result in unauthorized overwriting of victim invent | 9.6 | 0.05% | 2026-06-10 | 2026-06-10 |
| CVE-2026-53470 | A flaw was found in migration-planner. An authenticated attacker could exploit an improper access control vulnerability in the `/api/v1/sources/{id}/image-url` endpoint. This flaw allows the attacker to bypass an ownership check and obtain presigned S3 URLs for Open Virtual Appliance (OVA) images belonging to other users. Consequently, the attacker can download OVA images containing sensitive information, such as long-lived agent JSON Web Tokens (JWTs) and source configurations, potentially lead | 9.6 | 0.03% | 2026-06-10 | 2026-06-10 |
| CVE-2026-53469 | A flaw was found in migration-planner. An authenticated user can exploit this vulnerability by sending a DELETE request to the /api/v1/sources route, which lacks proper authorization and filtering. This allows for the destruction of all customer data, including sources, agents, and assessments, leading to a critical loss of availability and integrity across the entire SaaS platform. | 9.1 | 0.04% | 2026-06-10 | 2026-06-10 |
| CVE-2026-11884 | A heap buffer overflow flaw was found in 389 Directory Server. When serializing objectclass definitions, the oc_superior (SUP) field length is omitted from buffer size calculations in read_schema_dse() and schema_oc_to_string(), but the field is still written via strcat(). An attacker with Directory Manager privileges, or a compromised replication supplier, can trigger a server crash by creating objectclasses with long SUP values. This is an incomplete fix variant of CVE-2025-14905. | 6.5 | 0.04% | 2026-06-10 | 2026-06-10 |
| CVE-2026-11837 | A local privilege escalation vulnerability was found in the ansible.posix authorized_key module. The module's keyfile() function uses os.chown() instead of os.lchown() and opens files without O_NOFOLLOW when managing SSH authorized keys. An unprivileged local user can pre-stage symbolic links in their ~/.ssh directory to redirect file ownership changes to arbitrary system paths when an operator runs the authorized_key task as root, leading to local privilege escalation. | 7.3 | 0.02% | 2026-06-10 | 2026-06-10 |
| CVE-2026-11793 | A stack buffer overflow flaw was found in 389 Directory Server. The checkPrefix() function in pw.c copies an attacker-controlled algorithm ID into a 256-byte stack buffer without bounds checking when parsing reversible-encrypted attribute values. An attacker with Directory Manager privileges can crash the LDAP server by storing a crafted credential with an oversized algorithm ID. FORTIFY_SOURCE mitigates this to denial of service only. | 4.9 | 0.04% | 2026-06-09 | 2026-06-09 |
| CVE-2026-11792 | A heap buffer overflow flaw was found in 389 Directory Server. When audit logging is enabled, the create_masked_entry_string() function in auditlog.c copies a fixed-length password mask into a precisely-sized heap buffer without checking available space. If a short cleartext password is logged (requiring non-default CLEAR password storage or a compromised replication peer), the copy overflows the buffer, corrupting heap memory and audit log output. | 3.3 | 0.04% | 2026-06-09 | 2026-06-09 |
| CVE-2026-11790 | A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password storage plugin does not enforce an upper bound on the iteration count extracted from stored password hashes. A privileged attacker who can modify a user's password hash can cause excessive CPU consumption during authentication, resulting in denial of service. | 4.9 | 0.07% | 2026-06-09 | 2026-06-09 |
| CVE-2026-11789 | A flaw was found in 389 Directory Server. The SMD5 password storage plugin performs unsigned integer underflow when computing salt length from a crafted password hash shorter than 16 bytes, causing a buffer over-read that crashes the LDAP server during authentication. | 4.9 | 0.06% | 2026-06-09 | 2026-06-09 |
| CVE-2026-11788 | A flaw was found in 389 Directory Server. The dereference control plugin does not check for allocation failure before using a BER structure, allowing an unauthenticated remote attacker to crash the LDAP server when the system is under memory pressure. | 5.9 | 0.09% | 2026-06-09 | 2026-06-09 |
